Ning Cheng was a person with a strong sense of crisis, and he had always been very careful back in Jiangzhou. Now, realizing this, he immediately began refining Bigu Dan Medicine. He even took into consideration the potency of the Dan Medicine, choosing to refine only the lowest grade of Bigu Dan, each pill sustaining him for three days.
After refining two to three hundred pills, Ning Cheng started to wonder, what if he didn't die of hunger but thirst instead? Then he began refining Clear Water Dan Medicine. A single pill of Clear Water Dan was the size of a longan fruit but could condense the amount of a large bowl of water.
